o4 gto header install help? My girlfriend has a 04 gto a4. I picked up some brand new pacesetters long tubes for next to nothing. I have heard that you have to pull the steering rack to put them in. If so how hard is it to pull the rack. And is it ok to run the car without cats and no rear o2s until she can get a tune like the fbodys and vettes.

its a 6 out of 10. You are going to have to loosen up the the passenger side motor mount and completely remove the nut on the driverside and lift the engine about 5 inches.

Yes, you have to drop the rack. No, you don't have to lift the engine off the motor mounts. It's not super hard, just time consuming. It's a lot easier if you have access to a lift. I would also beg a buddy to help you, it's nice to have an extra pair of hands. You can run it until you get a tune. I'd leave the rear O2 sensors installed and plugged in. The worst that can happen is throw a code. It'll throw a code if you leave them off too.
